Abstract: As a threedimensional reinforced material, geocell has been widely used in many engineering projects such as residential and industrial buildings, highways and ports.Under the external loading, the geocell reinforced soils will subject to stress and will induce settlement. It is necessary to analysis the performance of the geocell reinforced soils and to estimate the foundation settlement value to ensure the project quality. The equivalent elastic modulus and other mechanical parameters of the geocellreinforcement are analyzed by the asymptotic homogenization method. The results indicate that the geocellreinforcement is an isotropic negative Poisson's ratio material in the transverse and longitudinal directions.Using the asymptotic homogenization method derived mechanical parameters for the settlement analysis of the reinforced soils with different geocell embedment. Both the numerical analysis and the field test results demonstrated that deeper geocell embedment would induce larger settlement.
